Those pirate ships aren't drawn and they aren't yours. Those are the pirate ships from Sins of a Solar Empire and those are just screen shots of them in game. You can even see the aliasing if you look closely.

If you meant that you are using them as a base then you should say that specifically because the info next to the picture makes it seem like you are taking all credit for them.

The drawing of the landing area, although impressive, is a barely altered version of the standard New London planet scene.

Most mods really only work on one version of the game, so chances are this one will only work on 1.005.
And your best bet for a successful game is to just start over and not use any saved games from before you installed the mod.

While I like the idea of recreating such a classic, I think people making these mods should put their own touch on the levels. Keep the basic layout but vastly expand upon the architecture, add new areas to the maps, make them different yet recognizable.

A few years ago an episode replacement for the first episode of doom was released and they did the stuff I mentioned above with just the doom engine. Here with half life, the engine can do even more and you should take advantage of that.

heres a link to that episode replacement, just to give you a specific idea of what I'm talking about.Doomworld.com
